To all whom it may concern.-

Be it known that we, SWEN PULSON and MARoUs L. SNOW, residents of Sterling, in the county of Vorcester, State of Massachusetts, have invented a new Improved Bushing for Emery-Vheels and similar Articles, of which the following is a specification.

Our invention relates to bushings used for holding the wheel to the arbor or drivingshaft securely, being specially adapted to Its nature is fully shown by the following description and accompanying drawings of a bushing embodying our invention. I

In said drawings, Figure l is a side view 0 the bushing with all parts in place, the broken lines showing the wheel or grinder. Fig. 2 is a cross-section on the line A B of Fig. 1, as seen from below. Fig. 3 isan end view of the sectional parts as seen from the right of Fig. 1, with the solid not C removed. Figs. 4 and 5 show a view of the wheel G and its opening, and a section of the same on line at y of Fig. 4.

D D D are three parts of a cylindrical bushing,having a screw-thread 011 their inner surfaces, into which the solid nut C is fitted, and each part provided with a curved lip or flange, D, fitting a straight groove, E, or space in the wheel G, and one or more of the C is a solid nut screwing into the sectionsD D D, causing them to fill the space made for them in the wheel, and, having a slightlyyielding collar, F, is screwed up tight, the rib E making it impossible for the bushing to turn in the wheel, the nut C being fitted to the arbor in any of the common ways.

7 Having thus fully described our invention, what We claim is The removable bushing described, consisting of the sectional parts, each having a partially-circular flange, and one or more of them provided with a rib longitudinally, in combination with a solid nut screwing into these parts, and awheel or similar article having a hole fitted for said parts and their projecting flanges and rib, substantially as described.

SIVEN PULSON.
